COOPERAGE-HOOP.

Specification of Letters Patent.

Patented May 12, 1908.

Application filed. May 21, 1906. Serial No. 317,860.

To all whom it may concern:

Be it known that I, LEO A. BRIGEL, Jr., a citizen of the United States, residingat Cincinnati, in the county of Hamiltomand State of Ohio, have invented certain new and usebarrel oasks, and similar objects of'coope'rage.

'One of its objects is to provide improved means for retaining hoops in place after thby have been driven to position.

Another object is to provide means for retaining the hoops in positiorfivhich will not interfere with driving or re-driving the hoops at any time.

Anotherobject is to provide a hoop fastening device which can be applied to old casks or barrels, as .well as to those in process of construction.

Another object is to provide meansxfor locally strengthening the hoops at'the point where the fastening is applied.

It further consists in certain details of form, combination and, arrangement, all ofresorted to to fasten the hoops in place upon cooperage work after they have been driven, such as driving nails into the stave along the edge of the hoop, providing ribs on the inner face of the hoop, etc. all of which have been unsuccessful.

As shown in the accompanyingdrawings, A, represents the barrel, (1 the 'staves and B' the hoops, which are severed or slit at b at,

two or more places for a short distance-,and a lip, C, caused to project inward by forcing of the metal of the hoop at the lip out of the plane of the hoop. he tendency, in driving the hoop is to force the lip back nearly into linewith the balance of the hoop, the lips however engage the staves and serve to prevent the hoops slipping backward and thus obviate the necessity to use chalk or rosin in driving. After the hoop has been driven to place, a blunt instrument may be employed series of slits cut lengthwise of the hoop, tongues projecting inward from one side of said slits to engage the staves to lock the to drive or sink the lip further into the face 0% the stave, thus firml -locking the hoop in place. Should it be desired atany time, the hoop may be further driven and again locked as above described. I preferably strengthen the'hoop at the point where the lips are formed by corrugating or forming ribs E therein, running lengthwise of the hoopiron, which assist in resisting and preventing damage'to the hoop during the driving operation. The

stamping or forming of the ribs E serves to increase the tensile strength of the-metal at this point and to assist in retaining the tongue in engagement with the stave. i Where it is desired to remove the hoop from the barrel after being locked, as above described, the same ma be done by. inserting a suitably formed tool' ,eneath the li s, .C, to

raise the same into line with the ba ance of the hoop and the hoop. is then driven off. While I regard the form of lip shown as the preferred and strongest form, the .outline of the lip may be'variously modified.

The device herein specified is capable of considerable modification Without departing from the principle of. my invention.

Having described my invention, what I claim is: r

.1. A hoop for the above purpose having a hoops in place, and a series of raisedribs arallel with the slits formed in the metal 0 the hoop at the opposite side of said slits. I

2. A hoop for the above pur ose having inwardly pro ecting lips forme integral with the hoop by slitting said hoop and bending the metal at one side of said slits, and reinforcing ribs opposite said slits fon the side from-which the hoo isto be driven.

3. In a device of t e character indicated, a hoop provided with a locking device formed by slitting the hoop and forcing the metal at onesideof said slit, after the hoop has been driven to place, into an inwardly rejecting lip and embedding said lip in'theace of the stav'es and a series of raised ribsparallel with and oppositesaid slits.
